Figure 6From: Eculizumab in paroxysmal nocturnal hemoglobinuria with Budd-Chiari syndrome progressing despite anticoagulation Sonographic images showing improved hepatic venous flow. (A) Ultrasonographic detection of partial recanalization of the right suprahepatic vein (“narrow pass image”). (B) Ultrasound Doppler evaluation of the right suprahepatic vein showing a continuous flow instead of a pulsatile signal. This is due to a proximal partial obstruction of the hepatic venous outflow.Back to article page
